The LINK SP1X4-4KUHD is a 1 x 4 HDMI splitter with scaler, reliably distributes one HDMI input signal to four outputs at resolutions up to 4K@60Hz 4:4:4 chroma sub-sampling. It follows HDCP 2.2 and HDMI 2.0b specifications, including supported data rates up to 18 Gbps, HDR (high dynamic range), 3D and HD lossless audio formats.

With the built-in scaler, when connected to different displays, the corresponding HDMI output is capable of scaling down automatically (down to 1080P) to feed an optimal output signal to its attached display.

The splitter provides HDCP management which continuously authenticates HDCP encryption between all devices, ensuring correct source content is output to each display. It also features automatic input cable equalization, actively conditions input HDMI signals to compensate for signal loss when using long cables or cascading multiple units.
